patch 9.0.2058: tests: avoid error when no swap files exist
Problem: tests: avoid error when no swap files exist
Solution: use unlet! so that no error message is reported
in case the variable does not exists
When s:GetSwapFileList() does not find any swapfiles, it will return an
empty list []. This means, that the variable 'name' will not be
declared, cause the following unlet command to fail and causing a 1 sec
delay on running the tests.
So let's instead use the :unlet! command which simply skips reporting an
error when the variable given as parameter does not exists.
